Your MacBook Pro model will determine which OS you can go to.
(From OS 10.6.8 you can go directly to OS 10.7, OS 10.8, or OS 10.9 but that depends on your hardware.)

Go to "About This Mac" under the "Apple" menu. Select "More Info" and then select "System Report". In "Hardware Overview" make note of the Model Identifier.

If the Model Identifier is MacBookPro1,1 or MacBookPro1,2 the maximum OS that can be installed is OS 10.6 (which you have).
If the Model Identifier is MacBookPro2,1 or MacBookPro2,2 the maximum OS is OS 10.7.
If the Model Identifier is MacBookPro3,1 or later the current maximum OS is OS 10.9.

(You probably have a MacBookPro3,1 or MacBookPro4,1 model since you have a 2.4ghz processor.)

All OS versions after OS 10.6 are installed through the App Store app (which you have on your Mac with OS 10.6.8). OS 10.9 is free and easy to find in the App Store app by typing "OS X Mavericks" in the search box at the top right of the App Store app window. To get OS 10.7 or OS 10.8 you need to first purchase a redemption code from the online Apple Store which will give you access to these OS versions in the App Store app.

Links to purchase redemption code for OS 10.7 and OS 10.8 can be found on these pages:
